Note
Unlike the PC200 BMS, we do not have control over the JK BMS firmware and software. If there are bugs in the JK BMS firmware or software, we can report them to JK and request a upgrade, but this is not always effective. Therefore, we cannot be held responsible for any issues caused by the JK BMS firmware or software. Our warranty is limited to the JK BMS hardware only.
Note:
1. The parts in the kit are designed for single-pole cells and dual hole cells.
2. This kit cannot be used with over-over-swollen cells. We recommend using cells from Gobel Power.
3. Internal cable size: Positive (ultra soft 10000 cores 50mm2 cable), Negative (ultra soft 5000 cores 2*25mm2 cable)

- EVE306Ah, EVE314Ah
The GP-SR1-Kit is a complete 16S build package for a 48V/51.2V LiFePO4 battery — everything except the cells:
- Battery case — durable server-rack style enclosure (White)
- JK 16S 200A BMS (JKBMS V19) with built-in 2A active balancer, Bluetooth monitoring, and CAN/RS485 communication
- LCD display screen, power switch, collection wiring harness, and communication board
- 200A circuit breaker (2P100A) for overcurrent and short-circuit protection
- Copper busbars, terminals, cables, epoxy sheets, and mounting screws
LiFePO4 cells are NOT included — purchase separately. The case and busbars fit EVE MB31 280Ah / 304Ah / 314Ah cells (also EVE 306Ah and various brands of 280Ah-class cells). Do not mix different capacities or cell versions in one pack (e.g. 280Ah V1 with V3 or 314Ah) — mismatched cells shorten pack lifespan and create safety risks.
Optional accessories: heating pad (2A/120W) for cold-climate charging and an external active balancer (4A/5A/10A) for higher balancing current.
Connectivity: the JK BMS ships with Bluetooth for close-range monitoring via the mobile app — it has no built-in WiFi. For remote online monitoring, add the optional WIFI module (bought separately), which connects the battery to the Gobel VRM platform.
2A balancing threshold: Yes, it is configurable. In the BMS host software or mobile app you can set the balancing start voltage — the 2A active balancer stays on standby until any individual cell reaches or exceeds your configured threshold, and automatically deactivates below it to conserve energy.
Screens and displays: JK screens are compatible with all JK BMS models, and the display wiring harness needs no DC-DC converter — JK handles it on the harness. If you prefer a BMS with stronger firmware support, our PC200 BMS version of this kit is developed and maintained entirely by Gobel Power.
The JK 200A BMS communicates over CAN or RS485, so the kit integrates with mainstream hybrid solar inverters (Victron, Deye, Goodwe, Growatt, Solis, Sofar Solar, etc.) in lithium battery mode.
If your inverter has no BMS communication input, configure it manually in lead-acid mode — no communication is required:
- Max charge voltage:
55.2V(3.45V per cell) - Max charge current:
150A - Max discharge current:
200A
The BMS provides real-time cell voltage, current, and temperature monitoring plus overcharge, over-discharge, and short-circuit protection in either mode, and the Bluetooth app lets you track the pack at a glance.
Shipping: this kit ships from EU stock in Germany — estimated 7–15 day delivery with free tax (VAT prepaid; no extra customs costs on delivery). Spare parts ship by UPS/DHL. 30 days free return to the local warehouse. Note: our EU freight forwarder does not issue VAT invoices, but you will not pay additional taxes.
Warranty:
- LiFePO4 cells: 10-year warranty on DIY kit cells
- JK BMS: 1-year warranty covering hardware only — the JK firmware and software are developed and maintained entirely by JK, so Gobel Power cannot be held responsible for JK firmware/software behavior
JK firmware notes (not hardware defects): SOC accuracy may vary between parallel battery packs, and the JK BMS does not support manual SOC calibration between packs — fully charge the pack to 100% at least once a month to keep SOC readings accurate and prevent drift. For full firmware support, choose our PC200 BMS version of this kit.
